Abstract
An apparatus for individually trapping atoms, individually imaging the atoms, and individually cooling the atoms to prevent loss of the atoms from the trap caused by the imaging. The apparatus can be implemented in various quantum computing, sensing, and metrology applications (e.g., in an atomic clock).
Claims22
An apparatus, comprising:
- an array of systems each having at least two energy levels that can be coupled by a coherent radiation;
- a source of the coherent radiation coupling the energy levels;
- a detector measuring an excitation probability of each of the systems 1n the array in response to the coherent radiation exciting or driving a transition between the two energy levels;
- a computer determining a detuning between a frequency of the coherent radiation and resonance frequency of the transition;
- and
- a modulator coupled to the source, wherein the modulator modulates the coherent radiation using the detuning so that the frequency of the coherent radiation 1s tuned to the resonance frequency for each of the systems in the array, so that the source 1s stabilized to the transition.
3 more elements
An apparatus, comprising
- a plurality of traps, each of the traps individually trapping one of a plurality of atoms in a different trapping potential;
- an imaging system individually imaging each of the atoms;
- and
- a cooling system individually cooling each of the atoms, wherein each of the atoms are cooled to prevent loss of each of the atoms from their respective trap caused by the imaging.
1 more element
A method of irradiating, comprising:
- providing or obtaining an array of systems each having at least two energy levels that can be coupled by coherent radiation;
- irradiating the system with coherent radiation, outputted from an oscillator, so as to couple the energy levels;
- measuring an excitation probability of each of the systems in the array in response to the coherent radiation exciting or driving a transition between the two energy levels;
- in a computer, determining a detuning between a frequency of the coherent radiation and resonance frequency of the transition;
- and
- modulating the coherent radiation using the detuning so that the frequency of the coherent radiation 1s tuned to the resonance frequency for each of the systems in the array, so that the oscillator is stabilized to the transition.
